Welcome to the Wiki

This wiki is the complete reference for the Aegis-Beacon project: the hardware, the firmware, the radio theory, and the field practice. It is organized so you can start with no prior knowledge and end with a working, field-tested rescue beacon.

How to use this wiki

• Start with the Onboarding section if you are new to radios, microcontrollers, or electronics.
• Move to Getting Started for the practical path: parts, flashing, first boot, first transmission.
• Use the search bar at the top of the wiki home to jump straight to any topic.
• Every article links to related pages; follow the chain instead of reading linearly.

What you will end up with

A pocket-sized radio beacon that transmits your position in Morse code on the 433 MHz band, built from about twenty off-the-shelf parts, costing between $23 and $28, and running for over 65 hours on a single 18650 cell.

Reading time

The full wiki is long by design: it is a reference, not a novel. If you only have one evening, read the quick start guide, flash the firmware, and do a bench test. Come back to the theory articles when you want to understand why each part works.
